Specification of Letters Patent.

Serial No. 703,037.

To all whom it may concern:

Be it known that we, EMIL Mnr'rnnn, S12, a citizen of the Republic ofSwitzerland, and residing at Gossau, Switzerland, and EMIL METTLER, Jr.,a citizen of the Republic of Switzerland, and residing at Romanshorn,Switzerland, have invented certain new and useful Improvements inEmbroidering-Machine Accessories; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

When embroidering large patterns as garments or the like which in theirwhole extension can be embroidered only by repeatedly reeling the fabricup, it happens, that when after completing a part of the pattern and thefabric is reeled up, the latter is distorted in lateral direction sothat the portion of the fabric continuing the completed portion of thepattern does not exactly join this portion but is somewhat spacedtherefrom. Also during the embroidering proper, as for instance in theperforating or punching, the fabric is unfavorably distort-ed in lateraldirection, so that at all events the neat appearance and the accuracy ofthe pattern is diminished and in many cases repeated em broideringbecomes necessary.

The object of the present invention is a device for the use in handorshuttle-embroidering machines, for preventing the fabric from beingdistorted by the embroidering or reeling.

In the accompanying drawing the inven tion is illustrated by way ofexample.

Figure 1 is a rear elevation showing parts of an embroidering machinewith a device according to this invention. Fig. 2 is a side elevation ofthe device. Figs. 3 and 4 are cross sections, showing the same atdifferent working positions.

The device comprises two wooden bars a and b, which are connectedtogether by hinges 0. Each bar is provided outside with pins d which arearranged at distances equal to the designs. The pins of the bar aproject at right angles to the surface of the bar (Figs. 3 and 4) whilethe pins of the bar 6 are rearwardly directed. The bars can be turned toform an angle with each other (Fig. 3) or to be stretched out in thesame vertical plane. In order to secure the bars in the latter position,a latch c is pivoted to the bar 7), which latch is mounted to engage thehead of a screw f in the bar a (Figs. 2 and 4).

The device when used is mounted above the surface to be embroidered andparallel to the fabric rollers. In order to attach the device to thefabric, the bars are moved into the angular position shown in Fig. 3.Firstly the pins of the lower bar Z) and hereafter the pins of the upperbar a are caused to penetrate the fabric. Then the bars are moved intothe position shown in Fig. 4 and secured in position by means of thelatch a. By turning the bars into this position the fabric is maintainedstretched in a vertical direction. The device remains in this positionduring the embroidering and the reeling operation and prevents thefabric from being distorted in the horizontal direction of the machine,the pins cZ fixedly holding the fabrics. As soon as the bars arrive nearthe fabric rollers, they are released from the fabric and displaced.I'Vhen removing the device the operations are performed in a successionreverse to that first described.

Of course several such devices are necessary for each story of themachine, the devices for each story being arranged side by side in ahorizontal row. The single devices may be of any suitable length and thedevices may at their joints simply oin or overlap each other or they maybe connected in any suitable manner.

We claim 1. In a device for preventing the distortion of the fabric inembroidery machines, a pair of rails directly flexibly connected attheir proximate edges and provided with pins at their opposite edges forpenetrating the fabric and holding it from distortion under allconditions of operation of the embroidery machine.

2. In a device for preventing the distortion of the fabric in embroiderymachines, a pair of rails directly flexibly connected at their proximateedges and provided with pins at their opposite edges for penetrating thefabric and holding it from distortion under all conditions of operation.of the embroidery machine, and means for holding the rails in engagingposition with the fabric.

3. In a device for preventing the distortion of the fabric in embroiderymachines, a pair of rails directly flexibly connected at their proximateedges and provided with pins at their opposite edges for penetrating thefabric and holding it from distortion under all conditions of operationof the embroidery machine, and means to hold the rails in the same planewhen in engagement with the fabric.

4. In a device for preventing the distortion of the stretched fabric ofembroidery machines, a pair of light rails hinged together at theirproximate edges, pins in their opposite edges spaced apart in accordancewith the repeat design, and means for latching the rails together inengagement with the fabric.

5. In a device for preventing the distor tion of the stretched fabric ofembroidery as our invention, we have signed our names in presence of twosubscribing witnesses.
